U.S. Rep. Duncan Hunter and Margaret Hunter, the congressman’s wife and former campaign manager, arrived to court separately but stood together while pleading not guilty Thursday to charges of illegally using the congressman’s campaign account for personal expenses.

The California Republican was met with chants of “Lock him up” by protesters when he arrived at the federal courthouse in downtown San Diego Thursday morning. Margaret Hunter arrived at the downtown courthouse separately. In court, the couple sat four seats apart.
